Outer wrap, absorbent core and backing
Diapers are mostly composed of the following parts: outer wrapping layer, absorbent core layer and base fabric.
1. Outer wrapping layer
The outer wrapping layer can keep the child's body dry, absorb urine quickly and prevent side leakage. Nowadays, most of the best-selling diapers in various shopping malls and supermarkets are non-woven fabrics. After wearing them, babies will not feel too much irritation. They are soft, friendly and comfortable.
2. Absorbent core layer
The main absorption layer is to use its capillary force to disperse the baby's urine to the entire surface layer, so as to quickly absorb, disperse and finally store the urine. In various supermarkets, the absorbent cores of the diapers we usually see are mostly layered, and are made of super absorbent resin and pure wood pulp.
3. Base fabric
Affected by price factors, the bottom of the best-selling diapers in China is mainly composed of breathable polyethylene film composed of high molecular organic compounds, while non-woven diapers have been used abroad because they are more comfortable and softer.
